To improve the catalyst utilization and reduce the catalyst amount, we designed the anode structure. The superior catalyst utilization of direct methanol fuel cell (DMFC) was obtained by localized catalyst loading on the reaction sites. Hence the multi-layer anode with localized catalyst loading was prepared by the sputtering method. The designed multi-layer electrode showed a high cell performance and mass activity because of the good contact at the interface between the catalyst and the electrolyte membrane and low mass transfer resistance. The ultra-low catalyst loading electrode preparing by the sputtering method was a very effective method for reducing the catalyst amount and enhancing the mass activity.
